Hi all,
The link that rdshores gave is the same link as above, but notice that there is a link to
this pdf datasheet on that page as well. Unfortunately, most of the details are in chinese in that file.
It does however, show a few graphs and schematics which lead me to believe that it is yet another clone of the AIC1642.
Also, a close comparison (as close as possible anyway) of the datasheets shows that the 2 chips have almost exactly the same ratings and are probably even pin compatible.
So.. This looks like it's probably the exact (or nearly exact) same circuit that's in everyone's favorite.. The Dorcy 1xAAA.
My guess anyway.
